in relation to some of the statements you've made Salman;
"The critical component of a Vintage Panerai is the movement"
I respectfully Disagree, the movement is only one component of a watch and for most vintage collectors, the history of the piece is more important together with the dial. I've seen but a few vintage pieces but in all instances the owner/s waxed lyrically about 'patina' and the curves/shape of the case.
"The movement is also essential as it forms nearly 50% of the value of the timepiece (and in the case of the Vintage Angelus powered Richemont issued PAM 203, 85% of the value of the watch)."
Not sure about this theory, it is well known the Angelus movements were acquired by OP from Sig. Ferretti at a very low price relative to the MSRP of the PAM203. Ocassionaly the debate about the value of a Panerai and the presence of an ETA movement occurs. Typically, this discussion concludes with consensus that the movement is not important, it's the DNA, the uniqueness of the Panerai case & dial.
My reading of Mr Ferretti's text is that there is no consistency in vintage movements, as during and after the war, parts were hard to source so "they had to dismount to take other parts needed to repair". Moreover, when Mr Ferretti states that " I believe that most of Vintage Panerai has undergone transplants more or less important" You can also read this to mean that a more typical vintage Panerai is one that has in fact been modified - the 'transplants' actually support authenticity. Ergo, there is nothing actually "odd" with the anomolies you document.
I have no issue with your opinion Salman, but I respectfully think you are on the wrong tram, hopefully these discussions can further illuminate everyone.
cheers
